Could this be WHY?

Could be Nerf. Although one can certainly do this, it may not be the best idea. Then again, it's not OP's fault for using it the way it was advertised.

Still, using a device like this while charging it can put too much stress on the innards. If it were me, I would just use a regular charger. It still sux for Op.

edit: Passthrough vaping only makes sense to me while in the car. I would want to be able to do this if I had to drive a lot
